In spite of the established link between parenting and adolescent sexual risk behavior, less is known about the role of adolescent gender as a potential moderator of this association. This literature review integrates findings from 24 studies to examine gender as a moderator of the link between parenting and youth sexual risk behavior. Although the link between parenting and adolescent sexual risk behavior is well established, much less attention has been given to understanding the moderating role of adolescent gender. Within this review, the term gender will be utilized. The purpose of this literature review is to determine whether gender moderates the relation between parenting and adolescent sexual risk behavior.

Sex, age and pathological conditions affect autoantibody correlation and hierarchical clustering signatures, yet many of the correlations are shared across all groups, indicating alterations to homeostasis. Our data characterizing the in vivo signatures of anti-GPCR autoantibodies thus suggest that they are a physiological part of the immune system.

However, these theories mainly aim to integrate the mechanisms of aab production with the commonly accepted paradigm that associates aab with autoimmune diseases. Thus, they are unable to fully explain the occurrence of self-reactive B cells in mice and humans 7 and the production of immunogobulin G IgG aab that are naturally present in sera from HD. The generation of natural aab shares a common ontogeny with that of conventional antibodies, as both depend on the presentation of stimulatory antigens by dendritic cells to T and B lymphocytes 4 , 6.

We hypothesize that, similar to the dysregulation of any biological process, such as the imbalance of cytokine synthesis by T helper Th cells in several pathological conditions 8 , the dysregulation of aab production and function may lead to autoimmune diseases. Thus, we suspect that the homeostasis of aab relationships, which are possibly a physiological part of our immune system, may break down, causing autoimmune disease.

We and other research groups have previously reported the existence of functional aab targeting G protein-coupled receptors GPCRs in patients with rheumatic diseases 9. GPCRs are the largest superfamily of integral membrane proteins in humans GPCRs play an essential role in vertebrate physiology by sensing the external environment of a cell and responding to a variety of physiological stimuli For instance, GPCRs coordinate the cellular behavior involved in host immune responses 12 by acting as chemokine receptors, thus functioning as pivotal regulators of cell migration and cell trafficking throughout the body.

In this context, GPCRs have been shown to interact with other essential physiological molecules by, for instance, cross-communication with growth factors and growth factor receptors by generating transactivation signals that contribute to the control of cell migration Here, our aim is to employ a stepwise, integrated systemic immunology approach to extensively characterize the correlation signatures of anti-GPCR aab across multiple chronic diseases and in a large cohort of healthy humans.

These aab also correlate with other aab directed against growth factors, growth factor receptors, and signaling molecules. Our data provide support to the concept that anti-GPCR aab are natural components of human biology. When the production of anti-GPCR aab becomes dysregulated, they may trigger the development of autoimmune diseases.

Since both elevated and decreased concentrations of aab have been associated with the development of immune-mediated diseases 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , we suspected that anti-GPCR aab are an intrinsic part of the immune system after observing altered levels of multiple anti-GPCR aab in sera from patients with different autoimmune diseases, such as SLE, SSc, GPA, and RA, compared with healthy subjects Fig.

Our analyses revealed disease-specific signatures of aab concentrations compared with those of healthy individuals. However, disease-specific changes among the other aab were identified. Relationships among autoantibodies in health and autoimmune diseases. The x -axis represents healthy controls. The median with interquartile range is shown in red.

Heatmaps of aab vs. In the correlation matrix, each small square represents a pairwise correlation between aab, as exemplified by d — h. The correlation matrices used to perform the hierarchical correlograms shown in Fig.

The aforementioned data suggested physiological relationships among aab. To gain better insights into this field of investigation, we expanded our study to include the analysis of HD sera for correlation networks among anti-GPCR aab and other aab groups e. As previously shown for a few types of aab 15 , we observed that HD aab targeting GPCRs strongly correlated with each other and with aab targeting growth factors and growth factor receptors Fig.

While gender and age slightly modified the relationship between sets of aab from HD Fig. Effects of gender, age, and systemic sclerosis on autoantibody correlations. To identify changes in the aab relationships of patients with non-autoimmune diseases, we analyzed aab correlations in conditions that are known to be associated with gender and age but of clearly different etiologies, such as OC and AD.

Of note, aab targeting neuronal receptors dopamine, adrenergic, muscarinic, and serotonin receptors showed strong intragroup relationships in both HD and patients with AD, further indicating the presence of physiologically related aab. While aab concentrations and their associations with clinical data from the AD cohort have been previously described 25 , detailed information regarding aab levels in sera from SSc and OC patients and correlations with clinical characteristics are being prepared.

The line width indicates the strength of the association, with stronger correlations indicated by thicker lines. Multiple connections of nodes indicate clustering. This approach revealed that the changes observed in aab relationships, as shown by the circular plots Fig. OC and HD vs. Autoantibody relationships reflect their concentration distribution patterns. Gini index confidence intervals were obtained by bootstrap analysis.

The red and gray shadows represent confidence intervals, and each small circle indicates the Gini index value. To further characterize the relationships among aab, we performed hierarchical clustering analysis of aab correlations. For comparison, Fig. The hierarchical clustering analysis of aab correlations revealed several clusters modules of aab in sera from HD Fig. We found several positive and negative clusters of correlations between various aab groups, supporting the modification of aab relationships by age and gender.

In the presence of SSc Fig. However, markedly changed aab hierarchical clustering was only observed when comparing aab from the SSc cohort composed mainly of females, mean age Aab from the SSc and OC cohorts were located in the bottom right corner of the correlogram matrix near the clusters of aab from HD females above and below 65 years of age, respectively. Taken together, these findings suggest that gender, age, and pathological condition influence the hierarchical clustering signatures formed by aab.

Heatmaps of autoantibody correlations. The color scale bar 0 to 1 corresponds to weak and strong correlations, respectively. Hierarchical clustering of the autoantibody correlation signature. Clusters of the correlations among aab are displayed in dendrograms on the top and side of the correlation matrix.

In the heat map matrix, each small square represents the pairwise correlations between aab. The correlation matrix used to perform the hierarchical correlogram of SSc is provided as source data.

To integrate the analysis performed using three cohorts of HD and patients diagnosed with different diseases and using different aab datasets, we performed a multistudy factor analysis MSFA In agreement with our hypothesis that aab acting under normal physiological conditions may become dysregulated under the influence of different variables, the MSFA revealed the presence of common and specific latent factors when comparing HD to patients with selected diseases Fig.

This finding implies that the specific factors we observed in the HD and disease cohorts are involved in particular physiological and pathological mechanisms, respectively. In contrast, the common shared factors suggest physiological functions that are regulated by aab but not affected by the disease state.

Multistudy factor analysis of autoantibodies. The images are heatmaps of estimated factor loadings of common and specific latent factors. Next, since an interactome database for aab is currently not available, we reverse-engineered aab functions through in silico evaluation of aab target interactions to gain insights into the dynamics of a putative aab network.

These findings suggest that HD-IgG controls the trafficking of neutrophils directly via chemotactic mechanisms and indirectly by triggering IL-8 production. A representative image of neutrophils white dots in the figure on the bottom surface of transwell plates is shown. Mouse images as well as syringe and membrane cartoons were adapted from Motifolio Drawing Toolkits www. EDNRA immunization was carried out by administration into footpads of 0.

In the control group, mice were treated with the same amount of membrane extract from untransfected CHO cells. Six weeks after the booster immunization, all mice were sacrificed for sample collection and quantification of anti-EDNRA aab. Error bars denote SD. However, IgG from the latter group showed stronger chemotactic activity and induced the formation of neutrophil aggregates when compared to IgG from non-immunized mice Fig.

With the discovery of anti-GPCR aab in patients with allergic rhinitis and asthma 33 and the recognition that they play a role in the pathogenesis of several disorders, such as rheumatic diseases 9 , the physiological relevance of aab targeting GPCRs found in the sera of HD 9 , 34 remains poorly understood.

The network-based analyses carried out in our investigation revealed distinct signatures of anti-GPCR aab in HD that are influenced by age, gender, and various diseases. These data are in accordance with our recently developed novel SSc mouse model, which is based on increasing the serum concentration of anti-AGT1R aab by immunizing mice with human AGTR1 manuscript submitted.

Therefore, our observations support the hypothesis that anti-GPCR aab are natural components of the immune system and may become dysregulated, triggering the development of autoimmune diseases.

This assumption is in accordance with the emerging observation of the role of the immune system in homeostasis beyond host defense 36 , 37 , 38 , 39 , Here, we determined the correlation signatures of aab in health and disease based on enzyme-linked immunosorbent assay ELISA , an approach that is widely used to determine the presence of aab that target GPCRs 9. Although this method is well established, there are limitations. The avidity and affinity of aab to their target are not measured. Of note, aab avidity and affinity, as well as aab isotype, can change the outcome of antibody—antigen interactions and relevant biological processes following binding.

As such, some biological determinants of harboring GPCR aab have not been measured for each aab in our study, which may be potentially relevant for all patient groups, including patients with autoimmune diseases. Consequently, it will be important to investigate the characteristics of the aab described above in HD to determine their influence on aab physiology.

For instance, low concentrations of aab could be compensated by high binding affinity and vice versa. We are also expanding our current findings by analyzing specific epitopes. Such experimental immunization also induces pathological SSc features, including interstitial lung disease and skin fibrosis.

Passive immune transfer studies would be a relevant next step to determine whether anti-AGTR1 indeed has pathogenic effects with respect to SSc. The presence of circulating aab in HD that target self-antigens, such as GPCRs, which are conserved among species 3 and form network signatures, expands our view of the immune system.

The prevailing concept of a functional immune system has focused on its role as a guardian against invading pathogens. An evolving shift backing off from this paradigm is derived from the notion that the immune system has evolved not only to protect the host from pathogens but also to maintain the immunological homeostasis of the organism.

As a consequence of internal tissue damage following infectious or noninfectious inflammation, this homeostasis can break down 36 , 37 , 38 , 39 , The current understanding of aab function is evolving and includes the notion that aab provide and maintain homeostatic functions through the binding of cellular antigens and consequently contribute to the clearance of apoptotic cells Aab production could be modulated by changing particular conditions, such as increasing or decreasing receptor expression, as demonstrated by injection with CHO cells overexpressing human EDNRA, thereby inducing anti-EDNRA antibody synthesis.

Consequently, the production and effect of these aab would depend on the level of receptor expression in specific tissues.
